Do I really need colyte (polyethylene glycol) before a colonoscopy?

Do I really need colyte (polyethylene glycol) before a colonoscopy?

Other options : There are many preps available. Options will vary with the endoscopist. It is best to discuss this with your doctor as he is the one who will advise you on the prep. A common option is a golytlely or CoLyte prep which involves consuming 4 liters of a peg solution. But options with MiraLAX (polyethylene glycol) and 2 liters of fluid are available. There is also a prep with pills. Check with your doctor for options. ...Read more

Different mechanisms: They have different mechanisms of action. Miralax (polyethylene glycol) is an osmotic laxative (draws water out). Dulcolax is a stimulating laxative and for best effect take tablet with full glass water on empty stomach. Severe ab pain or fever then urgently see a doctor.

Does bowel prep medicines relieve severe fecal impaction prior to colonoscopy procedure night before ?

Does bowel prep medicines relieve severe fecal impaction prior to colonoscopy procedure night before ?

Possibly: Bowel preps are taken to assure that the colon is relatively clean as the scope is passed so that even small lesions in the mucosa can be visualized. Many of the preps contain polyethylene glycol which absorbs liquid into the bowel. This may help but you may need a stool softner. ...Read more

Is colyte (polyethylene glycol) prep really needed before a laparoscopy?

Depends on...: Depends what the laparoscopic procedure is, also depends on your individual surgical risk profile and the comfort level of your surgeon. For example: for a tubal ligation it's probably not needed, for a retro peritoneal node dissection it is. I almost never use any bowel prep for the fertility and endometriosis surgeries i do. ...Read more

Scheduled for colonoscopy but afraid magnesium citrate won't clear my colon. Docqulace and bisacodyl failed to evacuate colon. Will the citrate work?

Scheduled for colonoscopy but afraid magnesium citrate won't clear my colon. Docqulace and bisacodyl failed to evacuate colon. Will the citrate work?

AlwaysAGuess; agent,: dose & response relationships with all the usual complex individual variables. A full bottle of citrate of magnesia will likely be far more effective than the other agents, especially if one stays physically active, fasts, take 2 days prior & chase with another bottle 1 day prior. Just keep up clear liquids. Awareness of heart beats both a focus & a self-distraction (from other greater) issues. ...Read more

Can I use enema instead of colyte (polyethylene glycol) for colonoscpy?

Not really: Colyte (polyethylene glycol) or any of the other accepted preps for colonoscopy clean the entire colon from above. Enemas don not adequately clean the entire colon. A clean colon is mandatory for a thorough colonoscopy. ...Read more

Can miralax (polyethylene glycol) change caliber of stool? Am being treated for constipation. Before miralax (polyethylene glycol) calibur was normal - with miralax (polyethylene glycol) stools are slow and thin.

Can miralax (polyethylene glycol) change caliber of stool? Am being treated for constipation. Before miralax (polyethylene glycol) calibur was normal - with miralax (polyethylene glycol) stools are slow and thin.

Oh my...: Before you contemplate long term laxative use, seek medical evaluation--rule out metabolic causes of constipation (e.g. Low thyroid or adrenal conditions), distinguish slow versus normal transit constipation, consider a primary rectal dysfunction that may be treatable with biofeedback, check for structural pathology or extrinsic impingement, or intermittent ileus (e.g. Pseudo-obstruction). ...Read more
